Answer to Question #847 in Quantum Mechanics for shadi
I would like to know that how can we write the commutation between Pj and a field?
I know the answer is "-ih d(field)/dx" but as Pj is in integral form I don't know how to prove it!
It's actually problem 2.4 of "quantum field theory " by mandle
